SWITCH-ACTUATING MECHANISM.

T 0 all whom it may concern:

Be it known that I, Josnrrr ARTHUR Bnannoni, a subject of the King of Great Britain, residing at Montreal, in the Province of Quebec, Canada, have invented certain new and useful Improvements in Switch-Actuating Mechanism; and 1 do hereby declare that the following is a full, clear, and exact description of the invention, such will enable others skilled in the art to which it appertains to make and use the same. I

The present invention relates to new and useful improvements in switch actuated mechanism.

The primary object of the invention is the provision of a switch actuating mechanism for street railways and the like, so designed that the switch will be automatically turned to the desired position upon the. approach ofa car thereto.

Another object of the invention is the provision of means for either opening or closing the switch upon the approach of a car thereto from either direction.

Still another object of the invention is the provision of electrical means for actuating the switch in the desired position upon the approach of a car thereto.

A still further object of the invention is the provision of a switch actuating mechanism controlled by a series of magnets, which derive their power from trolley wires, so arranged that the switch may be thrown to the desired position from any distant point, dependent upon the position of an operating handle actuated bythe motorman, so that the switch will be properly turned upon the approach of a car.

A still further object of the invention is the provision of a switch actuating mechanism, such as above referred to, which will be comparatively simple and inexpensive to manufacture, reliable and eliicient in use and readily operated.

With the above and other objects in view, the present invention resides in the novel features of construction, formation, combination and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawings, forming a part of the present application, and in which;

Figure 1 is a side View showing the invention applied to the usual street railway car; p

Figure 2 is a plan view showing the sw1tch; V

Figure 3 is a side View of a portion of the trolley;

Figure 4 is an end view of the trolley;

Figure 5 is a plan, view of a "portion thereof;

Figure 6 is-a diagrammatic view illus trating the complete wiring of the actuating magnets;

Figure 7 wiringof one set of magnets; and,

- Figure 8 is a similar view showing the wiring of the opposite set of magnets.

Figure 9 is a diagrammatical view illustrating the wiring of the magnets 15 and16.

Referring now to the accompanying drawings by corresponding characters of reference throughout the several views, the numeral 10 designates 1n general the tracksofa street railway line, in which the switch points are shown at 11. Each of the points 11 is pivoted to a disk 1.2, the rotation of which serves to open or close the switch as occasion might necessitate.

Apair of diametrically opposite arms 13 extend from each of the disks 12 and are provided with contact members 14: which are controlled by the magnets 15 and 16 arrangcd in alternate pairs as clearly shown in Figures 6, 7 and 8 of the drawing.

A street railway car is shown at 17 and maybe of anywell known or desired construction. This. car 17 is equipped with a trolley pole 18 provided with the usual trolley wheel 19 and additional trolley wheels 20 and 21 placed upon the opposite sides of the saidwheel 19. The trolley wheel 19 is designed to engage the usual trolley wire 22 for supplying current to the car, and'the supplementary or additional trolley wheels 20 and 21 which are spaced upon the opposite sides thereof are designed to engage each of the auxiliary trolley wires 23 and 23. respectively; Oneend' of the wire 23 is connected by the conductor 24; to the magnets 15 located for cooperation with the disks 12,

as is clearly shown in Figure 6, while one end of the trolley wire 23? is connected by the conductor 25 to the magnets 16. The opis a similar view showing the" posite ends of the magnets and 16 are both grounded to the track by the wires 26.

From the trolley wheels 20 and 21. lead the wires 5O and 80 which lead through the car as indicated in Figure 9. The ends of said wires are each connected to one of the switch contact points 29 and 29 A switch 29 is located in proximity to the motorman to cooperate with said contacts and 29*. A switch lever 29 is connected to the main line by the wire 30 and current is supplied from the trolley wheel 19.

From this construction it is obvious that ii? the motorman wants to turn his car to the left, he will throw the switch 29 in (3011- tact with the contact point 29*, and thus the current will he supplied to the magnets 15; and if so desired solenoids can he used instead oi. the ordinary electric magnet shown in the accompanying drawings.

-bviously when current is supplied to the magnets 15 by the proper conductors these magnets will he energized to attract the arms 1S and the disks will be rotated in the oirection shown in Figure 7 and when the V n'iagnets 16 are energised the disks will be drawn to the position shown in Figure 8 thus moving the switch points to their opposite position. The circuits in which the wires 23 are included lead through the car and either of the circuits maybe broken by means of the switch 29 which may be actuated by the motorman so as to throw the switch points to the desired direction upon the approach of his car.

It will be noted that the supplemental "olley wires 23 and 23 are only used as the car approaches the switch and otherwise only the trolley wire 22 is used in the cus ternary manner.

FlOll'iillG foregoing description taken in connection with the accompanying drawings it will be manifest that a switch actuating mechanism for street railway cars is provided which will i'uliil all oi the neces sary requirements of such a device, and it should be understood in this cot-inection, that various minor changes .in the specific (retails of construction can be resorted to within the scope of the appended claims,

without (ileparting from the spirit or sacrificing any of the advantages of the inventron. r

tHaviug thus fully described the invention what I claim as new and desire to secure by Letters Patent is:

1. The herein described apparatus comprising in combination with movable switch points, rotatable disks pivotally connected to the switch points, for throwing the switch points in opposite directions, and magnets for controlling the movements of said disks substantially as and for the purposes set forth.

2. The herein described switch operating mechanism including the combination of movable switch points, disk pivoted to said switch points, for moving the latter in opposite direction upon the rotation of said disks, magnets controlling the rotation of said disks, means "for supplying current to the magnets and means for changing the current to opposite sets of magnets and rotating the disks in opposite direction.

mechanism, including the combination with witch points, a disk pivotally connected to each of the switch points,-the disks being rotatably mounted, arms extending from said disks, magnets arranged in pairs for attracting the arms and rotating the disks in opposite direction, means for supplying current to the magnets, and means orreversing the current to the opposite magnets, substantially as and for the purposes set forth.

t. The herein described switch actuating mechanism, inchiding the combination with a s reet railway car, and a switch including switch points, of a trolley including additional wheels mounted upon the street railway car, supplemental trolley wires engaging said additional trolley wheels, magnets connected to said supplemental trolley wires for receiving current therefrom, disks operatively connected to the switch points, arms extending from the disks and controlled by said magnets, and a controlling mechanism mounted within the carfor controlling the current to opposite pairs oi magnets, for rotating the disks in opposite direction and properly moving the switch points. i V

5. The combination in an apparatus such as described with a switch and a street railway car said switch including movable switch points, disks pivotally connected to said switch points, arms extending from the disks, magnets arranged upon opposite idea of the arms tor actuating said arms, a trolley for supplying current to the magnets, and means for'controlling the current to opposite sets of magnets for attracting the arms in opposite directions and throwing the switch points in opposite direct ons, substantially as and. for the purposes set "forth.

In witness whereof I have hereunto set my hand.
